This invention relates to feeding ap aratus is adapted to convey such articles-which and more particularly to that type appahave already been sorted or separated by any ratus in which the articles;sorted in grades, suitable or well known means. The articles kinds or sizesare fed to a chocolate coatin are thus conveyed over the roller 3 and are or other treating machine or apparatus, an delivered on to the inclined plate or slide 4 55 in which the articles are shaken in order to which is preferably arranged at an angle bring them to an upright position while being somewhat less steep than the angle of inclinaconveyed on an endless band or the like. tion of the stationary slides heretofore em- In feedin apparatus of this type it has 'ployed in apparatus of this type.

In testimony whereof we have signed our the rod 16 relatively to the member 18 through the medium of the nuts 17.

In the arrangement shown, the said shaft 19- is driven by means of a sprocket wheel 24 from a chain 25 operated by a sprocket wheel 26 on the shaft 10.

As the feed band 1 is preferably driven by suitable sprocket or like means from the said shaft 10, the speed of delivery of the articles to the slide 4, and the shaking movement of the latter maintain their proper relation and the shaft 10 may be driven at any desired speed to suit the circumstances and conditions under which the operation is taking place.

It will be understood that the number of articles fed to the slide 4 depends directly upon the speed of the conveyor band 1, and it is therefore important that the shaking or jolting motion imparted to theslide 4 be so controlled that the articles are caused to travel over the slide 4 with greater speed when a greater number of articles are fed to the slide by the conveyor 1, and this regulation of the speed of the conveyor 1 in. proportion to the olting or shaking of the slide 4 is an important feature of the present in-' vention.

Although the drawing and the above Specification disclose the best mode in which we have contemplated embodying our invention, we desire to be in no way limited to the de- ,tails of such disclosure, for in the further practical application of our invention many changes in form and construction may be made as circumstances require or experience suggests without departing. from the spirit of the invention within the scope of the appended claims.

What we claim is:

1. Apparatus for supplying articles in an upright position having feed mechanism of bands for conveying the articles, an inclined slide interposed between the bands, means for shaking the slide and means for adjusting the amplitude of the shaking movement.

2. Apparatus for the supply of articles in an upright position having feed mechanism of the character described comprising an endless conveyor band for supplying the articles, an inclined slide receiving the articles from said band, means for jolting'the slide, and means for varying the amplitude of the j0lting movement imparted to the slide.

3. Apparatus for the supply of articles in an upright position having feed mechanism of the character described comprising an endfrom said band, means for jolting the slide,
